When Dev's character was introduced, he had all the resolve to bring out the truth of what actually happened to Payal and Nitya.
But he had all kind of obstacles from his family and his own mother.
He then meets Durga and some instincts (which even he is unable to realize) make him see Nitya in her or reminds more of Nitha which he is also unable to figure out.
So he had been shown digressing from his path of finding out about Payal and Nitya to knowing more about the mystery of Durga and her some connection with Payal and Nitya. He may for the moment be convinced that Durga found Payal in a transition camp and came to know about her story from Nitya's diary. But that is not the end to his curiousity about Durga.
He is puzzled about Durga's life - her love, her engagement.
Instinctively he is not searching for whereabouts of Nitya because he could feel her around him.
How could he keep away from Durga when she is Nitya herself.
He is now wavering from the truth Payal's story and Durga's life.
But Durga has given him enough hints to ponder about things going on. And to connect the missing pieces including the attack on his life.
Its time to show some kind of initiative and action from Dev.
Something which would connect Durga to Nitya.
Hope Dev's character is not wasted.
